I also remember that in Germany many events were on the brink.
It was said that we couldn't celebrate at such an event, which of course I could understand.
It was terrible...
Unfortunately, many theories were brought up, which unsettled one.
E.g. The Wold Trade Center was blown up, no airplane flown into the Pentagon, but a rocket and only parts of a small airplane that was only concerned with the gold, what was in the tower, etc.
You don't know what to believe.
I had a lot of respect for the helpers.
